Yea I know what you mean, but if you don't even understand what you are looking at then what is the point in trying to talk about it?  That was my point really towards the guy talking about 250V caps on a PC sound card.

Hi,
After help from Germanium an NCSUZoSo
 
i have all i need for my ZXR Mod:
2x DIP8 = AD8597
2x DIP8 = 2x ADA4627-1BRZ
2x 24uF ClarityCap PWA 160Vdc
3x 12uF ClarityCap PWA 160Vdc
 
Can u help me please i have questions for the shorted Cap from first Post.
I use a Beyerdynamic T70 Headphone
 

 The caps in the red box need to be shorted underneath the board. This is for the analog stereo output section of the card The caps in the blue box are for the surround sound analog output section. These only need to be shorted if you are using 5.1 speakers with analog input.

When i use a Headphone i must shorted the caps only in the red box?? or blu and red box???

Only need to short the caps shown with red short lines for stereo or headphones, other short lines are for surround sound. If you plan on doing surround sound at any time in the future it is best short them now. If you are sure you won't then leave those shorts out.

The reason you would want to do those shorts now if you plan on using the surround sound in the future is that it is strongly advisable to glue the film capacitors down to the board to prevent stress on the solder joints. This would make these short connections inacessable in the future so better to do it now.

sorry please delete. i understand it now many thanks

If you are going with the exact same op-amps as me you should use this guy unless you can do surface mount soldering:

That is who did mine (see pictures in thread).

 

[Stadtpirat]

Yes sir!
Your Sound setup with this ics are great for my Beyerdynamic T70
After a long search.
This Seller is the one and only i Found in the internet.
i wait over 2 Weeks, but the Taiwan post use a little boat and a slave for transport to germany.
And the ADA4627 are very hot, i plan a thermal pad between the emi shield and the dip8.
But i have a problem. Left Channel at 20 and the right channel at 30 % for real Sterreo. I think 1 of the 2 ADA4627 are damage.
Now i rebuy 2x and wait 2 Weeks and hope for real Sterreo.
 
I Buy the AD8597 at this guy

Very Fast delivery to Germany

Did you already return the opamp?  It's possible you just didn't have it seated completely or it just needs to be reseated.
 
I have actually used that ebay seller you linked, he does good work.

 

[Stadtpirat]

Yes i dont say the reseller sell dammage ic.
i seated the ic in the wrong direction, after no sound i change it.
i buy new ics, and in 2 weeks i use it in the right direction
 
Update:
My Mod

 
I hope it is right to remove all the caps

Now i build a Case
Sorry my englich is not good

 

[NCSUZoSo]

Try to get clear close ups of where those caps are soldered both on the top side and the bottom side.

 

[VelictAF]

Is that carpet? Build on a table D:

 

[NCSUZoSo]

That is true, static electricity is not your friend

 

[Stadtpirat]

 

 
I remove the caps and make a wire to the new caps. 12uF and 24uf ClarityCap Kondensator PWA and i shorted the red marked caps.
Nothing on the Backside. I asket for the caps on both sides (org + custom) or only on one side (only custom caps).
Yes it is carpet
static electricity is my friend but today it is hims free day
 
Update:
New Pic!
Update 2:
Sound is  very very very good
 
Update 3:
My 4x ADA4627-1BRZ arive
I have a question. I make my EQ Software like the Page 2. Can you say me please the value.

I wanted to see the solder points on the backside of the PCB, I realize they are going through the top of the PCB however the you soldered them on the backside.

 

[ModJPB]

Thanks for the mod!!!
 
I have done the bypass on the coupling caps (Red and Blue section) on all the channels. The sound is now more upfront!!! This solves the one complaint I felt about the sound from this card being distant. This part of the mod was fairly easy and well worth it for me. The only downside I noticed is the center channel now seems more dominant.? I had to lower the volume slightly on the center channel to fix this. Any ideas why?
 
I would like to do the decoupling capacitors (purple and green section) next, but finding space for them is very limited. Anybody have any ideas for doing this part of the mod but keeping it as compact as possible. When done I will report my impressions.
